Hi guys, i want move from my arduino nano to a stand alone proyect, im using a breadboard and a DIP atmega328 whit a AVR pocket programmer.
But i got a problem when i use a battery to power up the breadboard. If i use a simple blink led example, the program works fine, but when i upload my program, it only works fine if i put my finger in the ground line. My program works whit the MIRFv2 library to use a NRF24l01 (its not attached to the 328 yet) every 4 seconds the avr wakes up and send a data. In normal operation i see every 4 seconds a flash in the led connected to pin 19 of the atmega, but when i use a battery the led stay on until i touch whit my finger the grond lane, then works fine.
Any advice guys?
